RESET CIRCUIT
To reset the microcomputer, RESET pin must be held at an “L”
level for 20 cycles or more of XIN. Then the RESET pin is
returned to an “H” level (the power source voltage must be
between 1.8 V and 5.5 V, and the oscillation must be stable),
reset is released. After the reset is completed, the program starts
from the address contained in address FFFD16 (high-order byte)
and address FFFC16 (low-order byte). Make sure that the reset
input voltage is less than 0.28 V for VCC of 1.8 V.

Notes1: The frequency relation of f(XIN) and f(
φ) is f(XIN) = 2 × f(φ).
2: The question marks (?) indicate an undefined state that depends on the previous state.
3: All signals except XIN and RESET are internals.
